Kubernetes Requests and Limits - Presentation

2 weeks ago, as a DevOps engineer and part of the knowledge share and developer enablement at Camunda, I made across teams TechTalk about Kubernetes requests and limits, aka how to manage containers resources in Kubernetes.

As a container orchestration platform, Kubernetes provides a mechanism to manage the resources of containers in the cluster. That mechanism is known as "Requests and Limits".

Requests and limits play a key role not only in resource management but also in applications stability, capacity planning, and scheduling the resources (i.e., which pod will run on which node).

In this session, I've covered:

  • A quick review of Containers, Docker, and Kubernetes.
  • Containers resource management in Kubernetes.
  • Containers resource types in Kubernetes.
  • 3 different ways to set requests and limits.
  • The difference between capacity and allocatable resources.
  • Tips and recap.

Fortunately, I've also recorded the session in HQ (the actual slides only, less than 15 min!).

Kubernetes requests and limits are important and interesting topics for any SRE or DevOps engineer because, as mentioned before, they are vital for reliable Kubernetes clusters.

Enjoy :-)
